"Tried this upper with a few different lowers. Two different polymer lowers and a stag arms lower with a Jard trigger. It fired flawlessly all day. Upper needed cleaned out of the box. Metal shavings were throughout. ( makes it no different from the rest of the new guns I have purchased ) the bull barrel is heavy, but you should be expecting that if you buy a bull barrel. Standard mil spec carrier group (I heated and frog lubed mine when I got done cleaning, highly recommended). Other than weight, there are no negatives I have for this upper. Definitely worth the money."

"I selected this upper after reading the reviews of other Wilson barrels and conducting the other pertinent research for my first build. I was inexperienced with the caliber, as my other AR rifles use standard NATO cartridges. My apprehension was eliminated after the break in procedure produced consistent sub-moa results. The upper isn't sexy but it is very well made by a company that knows what they are doing. I really couldn't be happier with this purchase. The value and quality of this upper are beyond reproach and my next build will be a 24\" from the same company. You could spend more on barrel fluting, Teflon coating fancy hand guards etc... but if you just want a great shooting good looking well built no-nonsense upper, look no further."

"This is a very good buy. Took it to the range with my spare receiver and it performed as expected. At 50 yards I was getting 2\" groups with my EOtech X1 magnification. 100 yards next week. Got a magnifier for it and expect to do better than 2\". Does have some muzzle flash and noise but due to the weight of the barrel, very little muzzle flip. Tried it off-hand and on a tripod and still very accurate and manageable. Now I have the dilemma of whether I should take it to a gunsmith and have that beautiful barrel machined and threaded to accept a flash suppressor."
